CLAHY-DIGGER.

SPECIFICATION forming part of Letters Patent No. 232,674, dated September 28, 1880. Application filed July 3, 1880. (No model.)

To all whom it may concern:

Be it known that I, CARL BUSH, of the city, county, and State of New York, have invented a new and Improved Clay-Digger, of which the following is a specification.

The object of my invention is to provide a new and improved clay-digger which is simple in construction and effective in use.

The invention consists in a blade or landside of a plow provided with a flange at the bottom edge and a detachable mold-board at the rear edge, to which blade a beam and a handle united at their lower ends are attached in such a manner as to form a runner which passes over the surface of the ground, whereas the other parts out into the ground.

In the accompanying drawings, Figure 1 is a perspective view of my improved clay-digger. Fig. 2 is a plan view of the same.

Similar letters of reference indicate corresponding parts.

The front edge of the blade A is rounded and provided with an offset at its connection with the horizontal bottom edge of the blade at B. The blade is provided with a horizontal flange, O, at the bottom edge, which flange begins at the offset atB and extends outward on a curved line, returning to the blade and connected with it at the rear end of the said blade.

The blade A has a recess, D, along the rear edge, and the flange G is provided with a like recess, E. The edge of a curved mold-board, F, fits into either of the recesses D or E, and is attached either to the blade A or to the flange O by means of the countersunk screws G G A beam, H, and a handle, J, are made in one curved piece, and are attached to the blade A by two or more countersunk screws, K K, the said handle and beam at the same time forming a runner, L, which passes along the surface of the ground and prevents the blade A from cuttin g in too deep.

The device is used as follows: To make the first cut the mold-board F is attached to the flange C, as shown in Fig. 2, and the digger is then drawn over the field. The bladeA enters into the ground up to the runner L, and

earth that has been undercut by the flange O,

and the flange O cuts horizontally, as before, the mold-board loosening the parts that have been undercut by the said flange.

The within-described device may be used to cut and dig clay for brick-yards, potteries, 850., and may also be used to cut peat and the like.

Having thus described my invention, what 1 claim as new, and desire to secure by Letters Patent, is

l. A clay-digger made substantially as hereinshown and described,,and consisting of a runner, A, provided with a flange, (J, and a runner, L, terminating in the handle J and beam 'H, as set forth.

2. The combination, with the blade A, having a flange, O, of the detachable mold-board F, and the handle J and beam H, connected by the runner L, substantially as herein shown and described, and for the purpose set forth.

3. In a clay-digger, the blade A, constructed,

substantially as herein shown and described,

with a curved front cutting-edge, and having an offset, B, at the end of said curved edge and a rounded flange extending from the offset B to the rear end of the blade, as set forth.
